Board-to-board fit: 39 positions, single row, right-angle
The 39-position count is single-row. Confirm the mating header exists in this exact position count before committing the board layout.
No direct pin-compatible equivalent is listed in the Dubox series or from other manufacturers. The 39-position single-row count is niche; if you need a second source, consider a 40-position header (leaving one position unloaded) or contact us to cross-reference.
